| Subject: CVE-2024-57857: RDMA/siw: Remove direct link to net_device |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| RDMA/siw: Remove direct link to net_device |
| |
| Do not manage a per device direct link to net_device. Rely |
| on associated ib_devices net_device management, not doubling |
| the effort locally. A badly managed local link to net_device |
| was causing a 'KASAN: slab-use-after-free' exception during |
| siw_query_port() call. |
| |
| The Linux kernel CVE team has assigned CVE-2024-57857 to this issue. |

| Mitigation |
| ========== |
| |
| The Linux kernel CVE team recommends that you update to the latest |
| stable kernel version for this, and many other bugfixes. Individual |
| changes are never tested alone, but rather are part of a larger kernel |
| release. Cherry-picking individual commits is not recommended or |
| supported by the Linux kernel community at all. If however, updating to |
| the latest release is impossible, the individual changes to resolve this |
| issue can be found at these commits: |
